Adjustments

NOTICE: Urn should be up to temperature beforemaking adjustments of the brew system.

Brew Volume: Sprayover Time and RateTimer and sprayover rate are factory set. If othervolumes of water or a faster or slower sprayover rate isdesired, see following instructions:

Timer AdjustmentThe brew timer's full batch may be adjusted. Theadjustment screw is located behind the plug under thestart and stop buttons. See the figure below. Since thesprayover rate is constant, the length of brew time setsthe brew volume. The half batch is exactly 1/2 of the fullbatch.

Sprayover Rate AdjustmentPump Urns: models starting in 72, 73, 77, 82, 83, 87,93, CH, or suffix (P).A fixed orifice is located in top of spray arm swivel post.The only way to adjust the rate of flow from the sprayarm is to drill a larger hole for more sprayover water orreplace the existing orifice with a smaller hole size forless sprayover water.Heat Exchange Urns: models beginning in 74, 80, 81,84, 91, 99, without suffix (P).Heat exchange urns have a regulator which adjusts thesprayover rate. The adjustment screw is located underurn in the back of the control drawer on the left side,or inside the control box on the Midline Urns. SeeFigure A. Loosen, CCW, the screw to decrease flow andtighten, CW, the screw to increase the flow. The spraypattern should touch the weld line near the top of theliner.To set the sprayover rate, follow these steps:1. Divide the desired brew size by the desired brew

time. This is your sprayover rate in gallons perminute.

2. Operate the brew timer for one minute andmeasure the amount of water. If the volume ishigher than your sprayover rate from step 1,decrease the flow. Increase the flow if the volumeis too low.

3. Continue the adjustment until the desired rate isachieved.

Bypass Adjustment (Refer to Figure B)The bypass adjustment controls the amount of waterwhich bypasses the coffee during the brew. This waterdilutes the final brew. If bypass is desired, open redhandle on bypass valve. This opening will bypass up toabout 40% of total sprayover water. Each complete turnis approximately equal to 5% bypass.

Thermostat AdjustmentThe thermostat is factory set so that the maximumtemperature is about 200° F in heat exchange urns and195° F in pump urns. This is the high end of brew rangeon the thermometer and corresponds to the BREWposition on the thermostat. The HOLD position is thelow end of the brew range on the thermometer, or185°F.Water should never boil in the urn. If you need to adjustthe maximum setting of the thermostat, do thefollowing:1. Remove the thermostat knob.2. Insert small screwdriver into the center of the shaft.

Turn the screw slightly clockwise to decrease thetemperature.

3. Check the setting by adding cold water to makesure the temperature reaches the high end of theBREW range.
